Acadia National Park Managers’ Report
A citizen science early-detection summary
Welcome to the weekly early detection report of observations submitted
by iNaturalist and eBird users. These are all observations submitted
over the past week for species that Acadia National Park managers and
partners have identified as being of conservation interest. These data
for this report comes from two of the largest open source citizen
science projects: iNaturalist and eBird. The records included in this
report include both casual and research grade observations, so erroneous
identifications are possible. Users should double check the
identification of species to ensure they are correct.
